The Toyota 4x4 steel calipers that are bolt on for the S30 240Z are not the same as the Sumitomo MK63 calipers.The MK63 calipers actually started out on the older larger Prince luxo sedan and then were cleverly re-used as a factory option on the Nissan Works Z and Hako race cars.

The MK63 was also sold by Nismo for street use (with a solid rotor), in addition to the comp one with a vented rotor.

Today expect to pay about $750 - 1000 for a used / rebuilt setThey are prized because they are FIA legal for vintage motorsports

The factory ZR race cars actually ran 14x8.5 F and 14x11 R watanabes, and they got the calipers to fit... so.... you should toOnly question is offset that you would have to sort out with your specific wheels

On the hako parts interchangeability thread I listed front & rear wheel bearing part numbers - they were actually the same as later ZX cars if my memory serves me right - they were not 240Z...

Auto trans shifter opening looks small like this... see how mine was opened up to fit.See the visible larger seam in the sheetmetal? That's the larger manual trans opening. The auto's got an extra piece of sheetmetal spot welded on in the assembly line to accommodate their different shifter

I'm thinking about cutting out just the auto add-on, but then that's getting rid of a piece of history of the car...My shifter motion is not impaired by the smaller opening...

Just makes it hard on me to get a proper rubber shift insulating boot to minimize on exhaust fumes cause i've never seen an auto one available for sale. The usual hako vendors only seem to stock early and late style MANUAL rubber boots for the trans tunnel.

As for the brakes and suspension, it appears there is really no single car that shares interchangeability characteristics. Nissan sort of took bits and piece to makeup there product line but was vastly making changes to each. I will need to re-read the interchangeability thread.

I knew the MK63 brakes was a very cherished upgrade but did not realize they were a period piece for racing! Very cool modification!! Upon doing the MK63 front brakes was there any improving done to the rear?

I'm kind of thinking now that I might get ahold of Adam at feast (thanks Eric for that contact) and see about just tracking down some oe front rotors and caliper rebuild kit. As I want to take my car more to a restoration to stock more then a modification build. However, the MK63 brakes would be a nice touch to honor vintage racing!

Thank you all for your knowledge and contribution! Also, when I get the car back on stands I will be looking to see what my tunnel looks like!

I may be selling the rear rebuild kit same as the one Derux got from Adam at Feast... I'm upgrading to R32 all around. PM if your interested.

Hey Eric heres some pictures of the homemade flip down cubby in the lower section of the dash! It kind of really blows my mind the effort that was put into making it!!!

My camera really didn't want to focus on it, but the entire thing seems to be made out of 3 pieces of wood and then the wood laminate which is a slightly different grain then the stock wood grain. Might be the rubber-soul interior trim kit or equivalent!

And that high school wood shop class flip down cubby lid is almost more amazing than the real thing! Gives you an idea just how damn rare those things are that someone went to that much trouble... sensational!

Does your AC work? You probably saw my hako at JDM Legends. The AC didn't fit with my new headers so I asked them to just remove for now. My bay is looking really clean, but I may look into a custom AC kit next year. Let's see how much of the summer heat/humidity I can tolerate this season when I get the car here next week.

Oh I seen it!! Then drooled! Lol kind of sad when I got to JDML I sadly glanced at my car and walked up to yours in holy sh*t mode. BEAUTIFUL car, I then was able to go give mine some love before leaving it again to check out the shop RX7 and the GTR 4-door. So much to look at there shop, I could spend hours in there.

As for my AC not sure if it works or not, the blowers work but the air is very stale smelling so I just shut it off fast and haven't tried it since. Ill probably carefully remove the AC system abs box it up incase I want it down the line. But for now my little L20 needs all the help it can get and removing that drag along with the fan assembly would be helpful.

The S12+8 calipers fit the stock strut with stock rotors and a 14" rim clears it. I used to combo for years prior to moving up in wheel size and brakes. I still have the S12 calipers in my garage if you are interested.

Thanks for clarifying the MK63s are NOT solely works racing. The old PRESIDENT is the source for MK63s. A period correct upgrade but for the cost and performance value an unnecessary buy. The S12s are similar in performance.

Got some time to look over the car today, found some good and some bad. Mostly just bad, quite a bit of the underside of the car alarms me, however getting out the magnet and knocking on the areas it all seems to be pretty solid, i did find a couple spots of severe rust but they are in common areas so thats a relief. I suppose ill start with the good

I was alittle worried that the car started out as a automatic, however upon inspection it seems it indeed was born with a manual transmission!

Also on both the front and the rear bumper supports it appears to me that there was some fiberglass work done to them hopefully that there is some solid metal underneath the glass.

Next order of business is that someone must have wanted the chin spoiler to look "lower" then it is, so they made new holes and put it slightly lower then the original mounting holes were placed. Also the poor chin spoiler has really seen better days, really flimsy needs to be taken off and re-enforced.

And last but not least in the days discoveries is the trunk area. It has some sort of bumpy feeling under the paint, i took the magnet to it too and it has some sort of metal in it so its not entirely firberglass like i was suspecting. I think that it might have also been covered in the undercoating material before it was painted.

CCN (classic car Nagoya) is actually on JNC Forum and they have an amazing collection of used / rare parts... Definitely hit them up for whatever's missing in your cars. I got a nice un-molested radio/heater surround from them cause mine had been cut up by PO

SpiritGarage makes repro sheetmetal bits too, in Japan

I was just thinking out loud that someone stateside should start making sheetmetal... Would make it easier for us...

Last business in order was to make a coolant catch tank, it just has a hose that drains down onto the ground and after driving the car it will leak a couple drops nothing major, however i am kind of a neat freak and we have 2 dogs that are always in the garage so i don't want them to slop some of the coolant up. I made nothing permanent just a make shift one for now until i get a chance to find something either oem or custom built one.[/URL[URL=http://s151.photobucket.com/user/ClassicEF7/media/IMG_0879_zps9eeb012a.jpg.html]
